Treat wastewater to process water quality for cooling tower makeup, boiler feed, process washing, and irrigation — reducing freshwater consumption by 70-95%.
Water reuse treats industrial wastewater to a quality suitable for specific process applications rather than discharge. Reuse reduces freshwater consumption, lowers effluent discharge volumes, and cuts water requirements. The required treatment level depends on the reuse application: irrigation requires basic filtration; cooling towers need hardness and TDS control; boiler feed demands near-pure water. A typical reuse train includes biological/chemical conditioning and treatment, filtration, RO/NF, and disinfection. Multi-barrier design ensures reliability.
Most industrial wastewater streams can achieve 70-95% water recovery with appropriate treatment technology selection.
Water purchase, discharge fees, and energy requirements reduced by 40-70%. Typical project benefits 2-4 years.
Reduces dependence on municipal or surface water supplies, protecting against drought and scope increases.
Demonstrates sustainability commitment. Supports regulatory compliance and green certifications.
Step-by-step breakdown of the treatment process from influent to effluent.
Screening, equalization, and DAF remove solids, fats, and oils. Protects downstream membranes and biological processes.
Biological MBBR or chemical AOP reduces COD and BOD to levels acceptable for reuse. Target COD <50 mg/L for most reuse.
Media filtration, ultrafiltration, or cartridge filtration removes suspended solids and protects RO membranes. SDI <3 required.
RO or NF removes dissolved salts, hardness, and trace organics. TDS reduced from 2,000 to <200 mg/L for cooling towers; <50 for boilers.
UV or chlorine disinfection prevents biofouling in reuse piping. Treated water stored and distributed to reuse points with online quality monitoring.

No treatment stage operates in isolation. This process is designed to receive conditioned influent from upstream stages and deliver effluent quality suitable for downstream processes. Hydraulic and organic loading rates are balanced across the complete treatment train to prevent bottlenecking and ensure overall plant efficiency. Our engineers model the complete flowsheet to optimise Capital expenditure and Operating expenditure across the plant lifecycle.
Screening, equalisation, and pre-treatment protect this stage from damage and overload.
Effluent quality ensures downstream biology, filtration, or disinfection performs optimally.
Reject streams, filtrate, and centrate are routed back to appropriate upstream points.
Our engineers design and commission complete treatment systems including all equipment, automation, and commissioning support.
